In 4-[(4-chloro-3-nitro­benzo­yl)­hydrazino­carbon­yl]­pyridinium chloride, C13H10ClN4O4+·Cl−, the component ions are linked into a three-dimensional framework structure by a combination of three N—H⋯Cl and five C—H⋯O hydrogen bonds. In N-3,5-dinitro­benzoyl-N′-iso­nicotinoyl­hydrazine, C13H9N5O6, the mol­ecules are linked into a three-dimensional framework structure by one N—H⋯O and three C—H⋯O hydrogen bonds, augmented by an aromatic π–π stacking inter­action.

Comment

As part of our continuing studies of the supramolecular structures of hydrazones, we now report the structures of the title compounds, (I)[link] and (II)[link]. These compounds were initially prepared as part of a programme to test their bactericidal activities, especially towards the Mycobacterium tuberculosis bacterium. Both compounds were found to exhibit significant activities, which will be reported elsewhere.

In each compound (Figs. 1[link] and 2[link]), the N atoms of the hydrazine unit exhibit only very modest pyramidalization; however, the overall conformations are very far from being planar, as the leading torsion angles (Table 3[link]) readily show. The most striking difference between the two conformations is provided by the C17—N17—N27—C27 torsion angles; in both compounds, the nitro groups are also twisted out of the planes of the adjacent aryl rings. Hence, each mol­ecule exhibits no inter­nal symmetry, so that the mol­ecules are chiral. However, in each of (I)[link] and (II)[link], the space group accommodates equal numbers of the two enantiomers

[Scheme 1]

Compound (I)[link] is a salt in which the pyridyl N atom is protonated. The component ions are linked into a three-dimensional framework by three N—H⋯Cl hydrogen bonds, all involving the Cl1 anion as the acceptor, and five independent C—H⋯O hydrogen bonds (Table 1[link]). The structure also contains two fairly short C—H⋯Cl contacts, again both involving the Cl1 anion. The three-dimensional nature of the supramolecular structure can be demonstrated most simply in terms of a sheet formed by the three N—H⋯Cl hydrogen bonds only, and the linking of adjacent sheets via a cyclic motif involving just one of the C—H⋯O hydrogen bonds.

Within the selected asymmetric unit (Fig. 1[link]), pyridinium atom N11 acts as a hydrogen-bond donor to the Cl1 anion. Hydrazine atom N17 in the cation at (x, y, z) acts as a hydrogen-bond donor to the anion at ([{1\over 2}] + x, [{3\over 2}] − y, z), so forming a C12(9) (Bernstein et al., 1995[Bernstein, J., Davis, R. E., Shimoni, L. & Chang, N.-L. (1995). Angew. Chem. Int. Ed. Engl. 34, 1555-1573.]) chain of alternating cations and anions running parallel to the [100] direction and generated by the a-glide plane at y = [3\over4]. In addition, hydrazine atom N27 in the cation at (x, y, z) acts as a hydrogen-bond donor to the anion at ([{1\over 2}] − x, y, [{1\over 2}] + z), forming a C12(5) chain of alternating cations and anions running parallel to the [001] direction and generated by the effective c-glide plane at x = [1\over4] arising from the combination of the A-face centring and the explicit b-glide plane at x = [1\over4]. The combination of the [100] and [001] chains generates a (010) sheet built from a single type of R66(24) ring (Fig. 3[link]).

Two (010) sheets pass through each unit cell, generated, respectively, by the a-glide planes at y = [1\over4] and y = [3\over4], and adjacent sheets are linked by pairs of short C—H⋯O hydrogen bonds forming a cyclic motif. Aryl atom C26 in the cation at (x, y, z) acts as a hydrogen-bond donor to carbonyl atom O2 in the cation at (1 − x, 1 − y, z), thus generating an R22(10) ring centred at ([1\over2], [1\over2], 0) (Fig. 4[link]). Propagation of this hydrogen bond then links all of the (010) sheets into a single framework structure, which is further reinforced by the other C—H⋯O hydrogen bonds to give a three-dimensional structure of considerable complexity.

Since there are also two short C—H⋯Cl contacts within the structure (Table 1[link]), the Cl1 anion at (x, y, z) is surrounded by atoms N11 at (x, y, z), N17 and C13 both at (−[{1\over 2}] + x, [3\over2] − y, z), and N27 and C22 both at ([{1\over 2}] − x, y, −[{1\over 2}] + z). The H⋯Cl distances are within the sums of the van der Waals radii, although the inter­action energies are probably small. Atoms Cl1, N17vii, N27viii and C22viii [symmetry codes: (vii) x − [{1\over 2}], −y + [{3\over 2}], z; (viii) −x + [{1\over 2}], y, z − [{1\over 2}]] are effectively coplanar, and the overall coordination of atom Cl1 can be regarded as a distorted trigonal bipyramid, with atoms N11 and C13vii occupying the axial sites (Fig. 5[link]).

The mol­ecules of compound (II)[link] (Fig. 2[link]) are linked into a three-dimensional framework by a combination of one N—H⋯N hydrogen bond and three C—H⋯O hydrogen bonds (Table 2[link]), augmented by an aromatic π–π stacking inter­action. The formation of this rather complex framework can readily be analysed in terms of two one-dimensional substructures, each in the form of a chain of rings built from the co-operative inter­action of two hydrogen bonds.

Hydrazine atom N17 in the mol­ecule at (x, y, z) acts as a hydrogen-bond donor to the ring atom N11 in the mol­ecule at ([{1\over 2}] + x, [{3\over 2}] − y, [{1\over 2}] + z), so forming a C(7) chain running parallel to the [101] direction and generated by the n-glide plane at y = [3\over4]. At the same time, pyridyl atom C12 in the mol­ecule at ([{1\over 2}] + x, [{3\over 2}] − y, [{1\over 2}] + z) acts as a hydrogen-bond donor to carbonyl atom O2 in the mol­ecule at (x, y, z), thereby forming a C(9) chain along [101]. The combination of these two hydrogen bonds then generates a C(7)C(9)[R22(8)] chain of rings along [101] (Fig. 6[link]).

The [101] chains of rings are linked into sheets by a simple chain motif running parallel to the [001] direction. Pyridyl atom C15 in the mol­ecule at (x, y, z) acts as a donor to carbonyl atom O2 in the mol­ecule at (x, y, −1 + z) in a nearly linear hydrogen bond, so generating by translation a C(8) chain running parallel to the [001] direction. The combination of the [101] chain of rings and the [001] chain generates a (010) sheet, whose formation is further augmented by a single π–π stacking inter­action. The nitrated C21–C26 aryl rings in the mol­ecules at (x, y, z) and (2 − x, 1 − y, 2 − z), which lie in adjacent [101] chains offset along [100], are strictly parallel, with an inter­planar spacing of 3.342 (2) Å; the ring-centroid separation is 3.519 (2) Å, corresponding to a ring offset of 1.102 (2) Å.

Two (010) sheets pass through each unit cell; they are related to one another by inversion and are generated by the n-glide planes at y = [1\over4] and y = [3\over4], respectively. Adjacent sheets are linked into a single continuous three-dimensional framework structure by the final C—H⋯O hydrogen bond. Pyridyl atom C13 in the mol­ecule at (x, y, z), which lies in the (010) sheet generated by the n-glide plane at y = [3\over4], acts as a hydrogen-bond donor to nitro atom O51 in the mol­ecule at (1 − x, 1 − y, 2 − z), which forms part of the (010) sheet generated by the n-glide plane at y = [1\over4], so generating by inversion an R22(24) ring centred at ([1\over2], [1\over2], 1). The combination of the two hydrogen bonds having atoms C13 and C15 as the donors then generates a chain of edge-fused centrosymmetric rings having R22(24) rings centred at ([1\over2], [1\over2], n) (n = zero or integer) and R44(24) rings centred at ([1\over2], [1\over2], [1\over2] + n) (n = zero or integer) (Fig. 7[link]).

Experimental

Substituted nitro­benzoyl chlorides were prepared by treating the appropriate carboxylic acid (1 g) with thionyl chloride (3 equivalents), N,N-dimethyl­formamide (0.1 equivalent) and dichloro­methane (20 ml) at room temperature, under stirring and in a dinitro­gen atmosphere. After 6–8 h, the excess of thionyl chloride was removed under reduced pressure to leave the crude acyl chloride, which was used without purification in a reaction with iso­nicotinoyl­hydrazine (isoniazid, 1 equivalent) and, in the preparation of (II)[link] only, triethyl­amine (1 equivalent) in tetra­hydro­furan (20 ml) at 340 K.

For (I)[link], the systematic absences permitted Aba2 (= C2ca) or Cmca as possible space groups; Aba2 was selected and confirmed by the subsequent structure analysis. For (II)[link], the space group P21/n was uniquely assigned from the systematic absences. All H atoms were located in difference maps and then treated as riding atoms. H atoms bonded to C atoms were positioned geometrically, with C—H distances of 0.95 Å and Uiso(H) values of 1.2Ueq(C). H atoms bonded to N atoms were allowed to ride at the sites located from the difference maps, with N—H distances of 0.88 Å and Uiso(H) values of 1.2Ueq(N). The correct orientation of the structure of (I)[link] with respect to the polar axis direction was established by means of the Flack (1983[Flack, H. D. (1983). Acta Cryst. A39, 876-881.]) parameter.

Comment top

As part of our continuing studies of the supramolecular structures of hydrazones, we now report the structures of the title compounds, (I) and (II). These compounds were initially prepared as part of a programme to test their bactericidal activities, especially towards the Mycobacterium tuberculosis bacterium. Both compounds were found to exhibit significant activities, which will be reported elsewhere.

In each compound (Figs. 1 and 2), the N atoms of the hydrazine unit exhibit only very modest pyramidalization; however, the overall conformations are very far from being planar, as the leading torsion angles (Table 3) readily show. The most striking difference between the two conformations is provided by the C17—N17—N27—C27 torsion angles; in both compounds, the nitro groups are also twisted out of the planes of the adjacent aryl rings. Hence, each molecule exhibits no internal symmetry, so that the molecules are chiral. However, in each of (I) and (II), the space group accommodates equal numbers of the two enantiomers

Compound (I) is a salt in which the pyridyl N atom is protonated. The component ions are linked into a three-dimensional framework by three N—H···Cl hydrogen bonds, all involving the Cl1− anion as the acceptor, and five independent C—H···O hydrogen bonds (Table 1). The structure also contains two fairly short C—H···Cl contacts, again both involving the Cl1− anion. The three-dimensional nature of the supramolecular structure can be demonstrated most simply in terms of a sheet formed by the three N—H···Cl hydrogen bonds only, and the linking of adjacent sheets via a cyclic motif involving just one of the C—H···O hydrogen bonds.

Within the selected asymmetric unit (Fig. 1), pyridinium atom N11 acts as a hydrogen-bond donor to the anion, Cl1. Hydrazine atom N17 in the cation at (x, y, z) acts as a hydrogen-bond donor to the anion at (1/2 + x, 3/2 − y, z), so forming a C12(9) (Bernstein et al., 1995) chain of alternating cations and anions running parallel to the [100] direction and generated by the a-glide plane at y = 3/4. In addition, hydrazine atom N27 in the cation at (x, y, z) acts as a hydrogen-bond donor to the anion at (1/2 − x, y, 1/2 + z), forming a C12(5) chain of alternating cations and anions running parallel to the [001] direction and generated by the effective c-glide plane at x = 1/4 arising from the combination of the A-face centring and the explicit b-glide plane at x = 1/4. The combination of the [100] and [001] chains generates a (010) sheet built from a single type of R66(24) ring (Fig. 3).

Two (010) sheets pass through each unit cell, generated, respectively, by the a-glide planes at y = 1/4 and y = 3/4, and adjacent sheets are linked by pairs of short C—H···O hydrogen bonds forming a cyclic centrosymmetric motif. Aryl atom C26 in the cation at (x, y, z) acts as a hydrogen-bond donor to carbonyl atom O2 in the cation at (1 − x, 1 − y, −z), thus generating by inversion an R22(10) ring centred at (1/2, 1/2, 0) (Fig. 4). Propagation of this hydrogen bond then links all of the (010) sheets into a single framework structure, which is further reinforced by the other C—H···O hydrogen bonds to give a three-dimensional structure of considerable complexity.

As a result of the two short C—H···Cl contacts within the structure (Table 1), the Cl1− anion at (x, y, z) is surrounded by atoms N11 at (x, y, z), N17 and C13 both at (−1/2 + x, 1.5 − y, z), and N27 and C22 both at (1/2 − x, y, −1/2 + z). The H···Cl distances are within the sums of the van der Waals radii, although the interaction energies are probably small. Atoms Cl1, N17i, N27ii and C22ii [symmetry codes: (i) −1/2 + x, 3/2 − y, z; (ii) 1/2 − x, y, −1/2 + z] are effectively coplanar and the overall coordination of atom Cl1 can be regarded as a distorted trigonal bipyramid, with atoms N11 and C13i occupying the axial sites (Fig. 5).

The molecules of compound (II) (Fig. 2) are linked into a three-dimensional framework by a combination of one N—H···N hydrogen bond and three C—H···O hydrogen bonds (Table 2), augmented by an aromatic π–π stacking interaction. The formation of this rather complex framework can readily be analysed in terms of two one-dimensional substructures, each in the form of a chain of rings built from the cooperative interaction of two hydrogen bonds.

Hydrazine atom N17 in the molecule at (x, y, z) acts as a hydrogen-bond donor to the ring atom N11 in the molecule at (1/2 + x, 3/2 − y, 1/2 + z), so forming a C(7) chain running parallel to the [101] direction and generated by the n-glide plane at y = 3/4. A t the same time, pyridyl atom C12 in the molecule at (1/2 + x, 3/2 − y, 1/2 + z) acts as a hydrogen-bond donor to carbonyl atom O2 in the molecule at (x, y, z) thereby forming a C(9) chain along [101]. The combination of these two hydrogen bonds then generates a C(7)C(9)[R22(8)] chain of rings along [101] (Fig. 6).

The [101] chains of rings are linked into sheets by a simple chain motif running parallel to the [001] direction. Pyridyl atom C15 in the molecule at (x, y, z) acts as a donor to carbonyl atom O2 in the molecule at (x, y, −1 + z) in a nearly linear hydrogen bond, so generating by translation a C(8) chain running parallel to the [001] direction. The combination of the [101] chain of rings and the [001] chain generates a (010) sheet, whose formation is further augmented by a single π–.π stacking interaction. The nitrated aryl rings C21—C26 in the molecules at (x, y, z) and (2 − x, 1 − y, 2 − z), which lie in adjacent [101] chains offset along [100], are strictly parallel with an interplanar spacing of 3.342 (2) Å; the corresponding ring-centroid separation is 3.519 (2) Å, corresponding to a ring offset of 1.102 (2) Å.

Two (010) sheets pass through each unit cell; they are related to one another by inversion and they are generated by the n-glide planes at y = 1/4 and y = 3/4, respectively. Adjacent sheets are linked into a single continuous three-dimensional framework structure by the final C—H···O hydrogen bond. Pyridyl atom C13 in the molecule at (x, y, z), which lies in the (010) sheet generated by the n-glide plane at y = 3/4, acts as a hydrogen-bond donor to nitro atom O51 in the molecule at (1 − x, 1 − y, 2 − z), which forms part of the (010) sheet generated by the n-glide plane at y = 1/4, so generating by inversion an R22(24) ring centred at (1/2, 1/2, 1). The combination of the two hydrogen bonds having atoms C13 and C15 as the donors then generates a chain of edge-fused centrosymmetric rings having R22(24) rings centred at (1/2, 1/2, n) (n = zero or integer) and R44(24) rings centred at (1/2, 1/2, 1/2 + n) (n = zero or integer) (Fig. 7).

Experimental top

Substituted nitrobenzoyl chlorides were prepared by treating the appropriate carboxylic acid (1 g) with thionyl chloride (3 equivalents), N,N-dimethylformamide (0.1 equivalent) and dichloromethane (20 ml) at room temperature, under stirring and in a dinitrogen atmosphere. After 6–8 h, the excess of thionyl chloride was removed under reduced pressure to leave the crude acyl chloride, which was used without purification in a reaction with isonicotinoylhydrazine (isoniazid, 1 equivalent) and, in the preparation of (II) only, triethylamine (1 equivalent) in tetrahydrofuran (20 ml) at 340 K.

Refinement top

For compound (I), the systematic absences permitted Aba2 (= C2ca) or Cmca as possible space groups; Aba2 was selected, and confirmed by the subsequent structure analysis. For compound (II), the space group P21/n was uniquely assigned from the systematic absences. All H atoms were located in difference maps and then treated as riding atoms. H atoms bonded to C atoms were positioned geometrically, with C—H distances of 0.95 Å and Uiso(H) values of 1.2Ueq(C). H atoms bonded to N atoms were allowed to ride at the sites located from the difference maps, with N—H distances of 0.88 Å and Uiso(H) values of 1.2Ueq(N). The correct orientation of the structure of (I) with respect to the polar axis direction was established by means of the Flack (1983) parameter.
